Answer:

6 hours more

Step-by-step explanation

When Zoey started the flight the battery was 100%, then it dropped to 75% in 2 hours. So each 25% will last 2 hours and there is 75% remaining which if you divide by 3 it will give 1. And each 25% will last 6 more hours until the battery dies.

Answer:

a

  [tex]y(t) = 11e^{-\frac{t}{100} }[/tex]

b

  [tex]y(20) = 9 \ kg[/tex]

Step-by-step explanation:

From the question we are told that  

    The volume of brine in the tank is  [tex]V_L = 5000 \ L[/tex]

     The mass of the salt is [tex]y(0)= 11 \ kg[/tex]

     The rate at which water enters that tank is [tex]\r V = 50 \ L / min[/tex]

Generally the rate at which salt enters the tank is mathematically represented as

           [tex]z = \frac{0}{V_L} * \r V[/tex]

=>        [tex]z = \frac{0}{5000} * 50[/tex]

Here the zero implies that there is no salt entering the tank

Generally the rate at which salt leaves  the tank is mathematically represented as

           [tex]u = \frac{y(t)}{V_L} * \r V[/tex]

=>        [tex]u = \frac{y(t)}{5000} * 50[/tex]        

=>        [tex]u = \frac{y(t)}{100}[/tex]

Generally the rate of salt flow in and out of the tank is              

       [tex]\frac{dy}{dt} = z - u[/tex]

=>    [tex]\frac{dy}{dt} = - \frac{y(t)}{100}[/tex]

=>    [tex]\frac{dy}{y} = -\frac{dt}{100}[/tex]

=>    [tex]ln(y(t)) = -\frac{t}{100} + c[/tex]

at time  t = 0  y(0) =  11

=>  [tex]ln(11) = -\frac{0}{100} + c[/tex]

=>   [tex]c = ln (11)[/tex]

So

    [tex]ln(y(t)) = -\frac{t}{100} + ln (11)[/tex]

taking exponent of both sides

    [tex]y(t)=e^{ -\frac{t}{100} + ln (11)}[/tex]

=>  [tex]y(t) = e^{-\frac{t}{100} } * e^{ln(11)}[/tex]

=>  [tex]y(t) = 11e^{-\frac{t}{100} }[/tex]

Generally at t = 20 minutes

 The amount of salt in the tank is mathematically represented as

         [tex]y(20) = 11e^{-\frac{20 }{100} }[/tex]

=>      [tex]y(20) = 9 \ kg[/tex]

Answer:

Multiplying and dividing fractions are essentially the same process which you multiply the numbers straight across and no need for common denominators. Except in division of fractions, the second fraction is flipped so that the denominator is on the top and the numerator is on the bottom (reciprocal).

Step-by-step explanation:

Example:

[tex]\frac{3}{4} * \frac{1}{5} = \frac{3}{20}[/tex]

[tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{5} = \frac{3}{4} * \frac{5}{1} = \frac{15}{4}[/tex]

In the Arithmetic sequence, the common difference between consecutive terms is 3 .

The general term of an arithmetic sequence is,

                  [tex]a_{n}=a_{1}+(n-1)d[/tex]

where d is common difference.

Given that,  first term [tex]a_{1}=2,a_{3}=8[/tex]

So,       [tex]a_{3}=a_{1}+2d\\\\8=2+2d\\\\2d=8-2=6\\\\d=6/2=3[/tex]

Therefore, common difference is 3.

Answer:

Step-by-step explanation:

Paul's equation,

Since the given line is passing through a point (4, 2) and slope = -5,

y = mx + b

2 = -5(4) + b

2 = -20 + b

b = 22

Therefore, equation of the line will be,

y = -5x + 22

Seth equation,

Slope of a line passing through two points (x, y) and (4, 2),

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

-5 = [tex]\frac{y-2}{x-4}[/tex]

-5(x - 4) = y - 2

-5x + 20 = y - 2

y = -5x + 22

Therefore, both the equations represent the same line.

Answer:

1. [tex] h = -3t + 18 [/tex]

2. The amount of snow that accumulated the previous night.

Step-by-step explanation:

1. height of snow = h cm

time = t hrs

To determine the linear function, find the slope (m) of the line, and the y-intercept (b). Then represent the function in slope-intercept form as y = mx + b. Where,

y = h,

x = t

m = slope

b = y-intercept

Find slope (m) using points (6, 0) and (0, 18):

[tex] m = \frac{h_2 - h_1}{t_2 - t_1} = \frac{18 - 0}{0 - 6} = \frac{18}{-6} = -3 [/tex]

m = -3

The y-intercept is where the line intercepts the y-axis = 18

Substitute y = h, x = t, m = -3, and b = 18 into y = mx + b.

Thus, the linear function would be:

[tex] h = -3t + 18 [/tex]

2. The Initial value is the y-intercept, which is 18. In this case, 18 represents the amount of snow in cm, that accumulated the previous night.

Given:

The vertices of a polygon QRST are T(-2, 3), Q(1, 5), R(3, -1) and S(0, 0).

To find:

The vertices for [tex]R_{x-axis}(QRST)[/tex].

Solution:

The rule [tex]R_{x-axis}(QRST)[/tex] represents refection of polygon QRST across the x-axis.

If a figure is reflected across the x-axis, then

[tex](x,y)\to (x,-y)[/tex]

Using this rule, we get

[tex]T(-2,3)\to T'(-2,-3)[/tex]

[tex]Q(1,5)\to Q'(1,-5)[/tex]

[tex]R(3,-1)\to R'(3,1)[/tex]

[tex]S(0,0)\to S'(0,0)[/tex]

Therefore, the vertices for [tex]R_{x-axis}(QRST)[/tex] are T'(-2, -3), Q'(1, -5), R'(3, 1) and S'(0, 0).

Rx-axis means that the polygon QRST is reflected across the x-axis.

The ordered pair after Rx-axis is Q'(1,5), R'(3,1), S'(0,0) and T'(2,3)

The points are given as:

[tex]\mathbf{Q = (1,5)}[/tex]

[tex]\mathbf{R = (3,-1)}[/tex]

[tex]\mathbf{S = (0,0)}[/tex]

[tex]\mathbf{T = (-2,3)}[/tex]

The rule of reflection across the x-axis is:

[tex]\mathbf{(x,y) \to (x,-y)}[/tex]

So, we have:

[tex]\mathbf{Q' = (1,-5)}[/tex]

[tex]\mathbf{R' = (3,1)}[/tex]

[tex]\mathbf{S' = (0,0)}[/tex]

[tex]\mathbf{T' = (-2,-3)}[/tex]

Hence, the ordered pair after Rx-axis is Q'(1,5), R'(3,1), S'(0,0) and T'(2,3)

Explanation:

1/3 is the same as 2/6

Imagine cutting a cake into thirds, then cutting each piece in two parts, so you'll have 6 pieces total. If you shade one third of the cake, then this is the same as shading 2/6 of a cake. The diagram shows this below.

Therefore 4/6 + 1/3 is the same as 4/6 + 2/6

At this point, we add the numerators over the common denominator

4/6 + 2/6 = (4+2)/6 = 6/6 = 1

Meaning we get a full cake since 4/6 is four slices and 2/6 is another two slices leading to 4+2 = 6 slices total out of the 6 overall.
